This invention relates to knittin needles adapted to be manipulated byhan or in a machine for repairing runs in knitted fabrics such ashoisery, and more particularly relates tothe latch construction of sucha type of needle.

One of the great difficulties encountered with knitting needles usedfor'the repairing ofruns in fabric has been the failure of the latchmember to remain in its retracted or open position when thrown upwardlyby a thread of the run being repaired, a suflicient length of time so asnot to interfere with the engagement of the hook of the needle with thenext cross thread of the run. In needles heretofore constructed there isa tendency for the latch to jar out of, or become displaced fromitsretracted position prematurely and thus prevent the proper or rapidoperation of the needle.

It is the object of the present invention to provide a construction oflatch member which will frictionally retain itself in open position, orin fact, in any position it is moved, with respect to the shank, by athread of the run being repaired.

Further objects of the invention will appear more fully hereinafter.

The invention resides substantially in the structure hereinafterdescribed, as illustrated in the accompanying drawings, and pointed outin the appended claims.

Referring to the drawings:

Figure 1 is a front elevation of a needle constructed in accordance withmy invention showing the latch member in closed position.

Fig. 2 is a view in side elevation of the needle also showing the latchmember in closed position.

Fig. 3 is a viewin transverse section taken on the line 33 of Fig. 2looking in the direction of the arrows.

Fi 4 is a top plan view of the latch mem er.

Fig. 5 is a side view of said latch member.

The needle comprises a shank portion 1 which terminates in the hook 2.If the needle is operated by hand the shank is secured to a suitablehandle (not shown) so that it can u be more readily operated. In casethe needle is used in a run repairingmachine the shank is secured in theusual manner to the needle bar thereof.

The shank is provided wit-h a slot 3 which 1ios adlapted to pivotallyreceive the latch mem- The latch member comprises a resilient piece ofmetal which is slit into two fins 5 and 6 and is formed with a hoodortion 7 adapted to contact with the point 0 the hook portion 2. A hole8 is provided in each of the fins 5 and 6 which is adapted to receivethe pivot pin 9 secured in the shank.

The fins 5 and 6 of the latch member are separated from each othersufiiciently so that a slight pressure is necessary to bring their facestogether and when such pressure is released they will have a tendency tospring away from each other.

In assembling the latch member with the needle shank the resilient finportions 5 and 6 thereof are pressed together so as to fit in theslotted portion of the shank and the pivot pin inserted through the hole8 thereof.

When the pressure is released from the fins the flat side faces of thefins spring'into frictional engagement with the inner side faces of theslot 3.

It will be seen that due to the frictional pressure exerted by the facesof the fins against the inner faces of the slot that the latch memberwill tend to stay in any position it is moved around the axis of thepivot pin 9 and will retain this position until forced therefrom by theaction of a thread of the run being repaired.

By such a construction of the latch member there is no liability of thelatch dropping to closed position or partially closed positionprematurely and it is necessary in order to change the position of thelatch to force the same manually or by means of a thread to a newposition.

Having now described my invention, what I claim as new and desire tosecure by United States Letters Patent is:

1. A run repair needle having a hook portion and a slotted shank portionwith a pivot pin in said shank portion, in combination with a latchmember having a hood to protect said hook and resilient fins' extendingfrom said hood to said Fivot pin tofrictlonally engage the sides 0 saidslot.

2. A run repair needle having a hook portion and a slotted shank ortionwith a p1vot pin in said shank portion, in combination with a latchmember comprisin a hooded body part and divergin fin mem ers tofrictionally engage the si es of the slot about said pivot pin.

3. A latch member for run repair needles having a slotted shank, saidlatch member comfigrising a head having a cavity and a pair of sdiverging from said head, said fins resiliently engagmg the walls ofsaid slotted shank.

4. A latch member for run repair needles comprising a hood like head andtwo diverging fins extendinghtherefrom.
